PETER H. MURPHY, OF ST. LOUISQMIS SOURI.

' OUTSIDE CAR-ROOF.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed May 17, 1905. Serial 110.260,?56.

To all whom it may concern:

Be it known that 1, PETER H. MURPHY, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Improvement in Outside Car-Roofs, of which the following is a specification.

My invention consists in the parts and the arrangements and combinations of parts hereinafter described and claimed.

In the accompanying drawings forming a part of thls speciiicatlon and wherein like symbols refer to like parts wherever the occur, Figure 1 1s a plan view of a car r00 parts being broken away to show the constructron; Fig. 2 IS a perspective View showing the unction at the corners of four of thesheet metal sheets covering the roof; Fig. 3 is a plan view of a blank for one of the sheets the lines along which it is bent being indicated in dot-and-dash lines; Fig. 4 is aperspective view of the upper end of the blank after one of the side flanges has been bent up and rebent; Fig.5 is a perspective view of the upper end of the blank afterthe top flange has been bent up and rebent; Fig. 6 is a ers ective view of the u per end of the blan: a or the second side flhnge has been bent up and rebent and, Fig. 7 is a perspective view of the finished sheet.

The wooden portion of the car roof com-- prises carlines 1 resting upon beams 2 at the sides of the car'and connected to a ridgepole 3. Upon the car-lines rest beams 4 running longitudinally of the car and upon these boards 5 are secured. This wooden construction is covered with metal sheets 6. The metal sheets preferably used extend from ridge to caves and are provided with substantially vertical rtbent flanges at the sides and at the top. The side flanges of ad'acent sheets overlap and form a watertiglit joint while the top flanges of sheets upon opposite sides of the roof, and meeting at the ridge, overlap and form a water tight ioint.

N either the side nor the top flanges have their rebent portions extending entirely to the corners of the sheet. The rebent portion of the flanges is cut away a short distance from the corner. The flanges themselves, however, extend entirely to the corners and the surplus portion 7' is bent around the corner. Thus the upper corners consist of solid metal and there is no pe1fo ration at any point, noris there any necessit ;l for soldering to render the corner Watertig t. I

, A casting ,9 fits over the meeting corners of the sheets atthe ridge of the roof and overlaps the rebent portions of the flanges. This casting thus performs the function of the rebends of the flanges for the corners which are without rcbends, as well as other functions hereinafter appearing.

The runnmg-b'oard is secured on the roof without perforating the metal sheets in the following manner: Gross pieces 10' which are grooved on their lower sides to accommodate the seams between the sheets, fit over the seam and the castings 9 and are secured by a bolt 11 passing through the cross-pieces, though holes 12 in the castings 9 and through the ridge pole 3. Upon these cross-pieces, the running-boards 13'are secured.

The lower end margins 14 of the sheets are bent downwardly and fit over the eaves of the car. They are securedby clips 15 which extend over the lower ends of the sheets and are fastened to the molding strip or side of the car below the edge of the bent margin.

A specially constructed blank is used to make the sheet described above. At the lower corners of a rectangular sheet of metal oblong notches 16 are cut out. One dimension of said notches is substantially equal to the width of the rebent flange and the other dimension is substantially equal to the ownwardly width of the downwardly turned lower niarv of the sheet. The side 21 makes an angle a little greater than a right angle with the side and stands perpendicularly to the side 18.

The flanges are bent up and re-bent ata single operation in a bending. machine. Preferably the right flange 22, as you face the Lop of the sheet, is bent up and rebent as illustrated in Fig. 4. Then the top flange '23 is bent up and-re-bent as illustrated in Fig.

.-). The surplus metal 7 at the corner of the sheet, in line with the portion of the margin forming the llanges, projects in a point. The h-lr flange 24 is then bent and rebent as illustrated in Fig. 6, leaving a second point projecting from this corner. The margin at the bottom of the sheet is then bent downwardly, the points 7 are hammered flat upon the faces of the flanges and the sheet is complete as illustrated in Fig. 7.

By shapingithe notches. as shown, the top edges of the points necessarily slope-down- \\"a1"dly from the top edges of the flanges. It will thus be impossible for the points 7 to ex- :r-nd above the top of the flanges when the sheet is finished even when the bending is inaccurately done. A projection extending above the top edges of the flanges would be objectionable as it might prevent the it of the castings over the corners of the sheets. Had the edges 19 and 20 of the notches 17 been atright angles to each other such a projcction could have been avoided only by very careful workmanship in the practice of accurate, slow and, consequently, expensive methods.

Obviously, the construction is capable of modification within the scope of my inveniion and therefore I do not wish to be limited to the specific construction shown and de-' scribed.

What I claim as my invention and desire to secure by Letters Patent is:

1. An out-side car roof comprising a supporting structure, sheets extending from said rid go to eaves, each of said sheets having rebent flanges atthe top and sides, the cornew inl'i'lled by said rebcnt flanges being intog-furl, the reheat side flanges of adjacent sheets interlocking with each other and the l'tjll ulll top flanges of sheets upon opposite sides of the roof interlocking with each other, lro ss' pieces extending over the corners of said sheets at the ridge of the roof and bolts passing through said cross-pieces and down to said supporting structure, said bolts passing between the adjacent corners of the sheets.

2f An outside car roof comprlsing sheets extending from ridge 'to eaves and having ire-bent l'langes at the top and sides, all of said flanges being rc-bent outwardly and the re-bcnt portion of said flanges being cut off short of the corners formed by said flanges, and said corners being integral, the re-bent side flanges or adjacent sheets interlocking with each other and the re-bent top flanges of sheets upon opposite sides of the roof interlocking with each other.

3. An outside car roof comprising sheets extending from ridge to eaves and having flanges at top and sides, all of said flanges being re-bent outwardly, and the corners formed by said flanges being integral, the surplus metal at said corners lying along the face of one of said flanges, the re-bent portion of said flanges being cut away from said cor- 11ers a distance at least equal-to the extent of said surplus metal along the faces of the flanges, said sheets being secured together laterally by the interlocking of adjacent side flanges and secured together at the ridge of the roof by the interlocking of the top flanges of sheets upon opposite sides of the roof.

-t. An outside car roof comprising sheets extending substantially from ridge to eaves, each of said sheets having re-bent flanges at the top and side edges, the corners formed by said flanges being integral, and the re-bent portions of said flanges stopping short of said corners, the re-bent side flanges of adjacent sheets being arranged to interlock with each other and the rc-bent top flanges of sheets upon opposite sides of the roof being arranged to interlock with each other.

5. An outside car roof comprising sheets extending substantially from ridge to eaves, each of said sheets having re-be'nt flanges at the top and side edges, the corners formed by said flanges being integral, the re-bent portions of said flanges stopping short of said corners, and the upper edges of said flanges near said corners being inclined downwardly toward said corners, the re-bent side flanges.

5. A car roofing sheet bent upward on top and side edges thence bent outward and downward, the upward bend of the side edges extending beyond the line of the first bend on the top edge, said extending side portions being bent against the wall of the first bend of the top edge and one side respectively of the sheet.

10. A car roofing sheet having rebent top and side flanges, the rebent portion being cut away a short distance from the corners, the flanges extending entirely to the corners and the surplus material bent around the corner 11. A car roofing sheet having rebent top and side flanges, the rebent portion being cut away a short distance frong the corners, the flanges extending to the corners and the surplus material bent around the corner against the top flange and deflected below the top of the top flange.

12. A blank for car roof sheets having side and top portions constructed to be rebent,
